REPORT ON FISHES. PART II: SISORIDAE AND CYPRINIDAE 



The Yale North India Expedition obtained 10 specimens from the following localities: 



Dal Lake. Lokut (Sta. K 3), ca. 5.190 ft 3 (55- 62 mm.) 



Srinagar (Sta. K 7), ca. 5,200 ft 7 (62-108 mm.) 



Of these 10 specimens, 3 taken at I.nkut Dal Lake, are l)adly desiccated and shrivelled. 

 The majority are females either with ripe eggs or fairly matnre gonads. The species seUlom 

 exceeds 150 mm. in length, and apparently attains se.xual maturity at 30 tn 45 mm. stage 

 (Mukerji, o/'. cit.). The tish is of a stout and thick huild with a snmewliat deep body and 

 a liroad and blunt snout. The position of the vent is from 3 tci 4 scales in advance of the 

 in.'iertion of the anal fin. In small specimens the \cntrals extend as far ;is the vent, Imt 

 in larger full-grown individuals they just miss it. 



The colouration of the specimens in alcuhcil \;iries tmni dark hi'dwii {n dusky with 

 a darker upper half. In medium sized specimens of 30 to 70 mm. in length, the scales 

 are sometimes infuscatcd with fine black dots. All the fins are diajjlianous. 



Bionomics: The peritoneum is black. The length of the air-bladder is contained about 

 3.5 times in the length of the body excluding the caudal iin. The posterior chanil)er is 

 long and narrow with a sharp end; it is of uniform thickness and its length is almost twice 

 that of the anterior chanil)er which is somewhat of a knob-like structure (Text-figure 2).
